Current evaluation

Feature request to allow pinning a specific snap revision in build-snaps/stage-snaps (currently only channels like 8.0/edge are supported). Unimplemented in rockcraft/craft-parts; no maintainer triage, but recent user comments show continued demand.

Suggested action: needs triage

Reason: No labels, assignee, or maintainer response — only two external user comments (2024-01-24, 2024-07-15) expressing demand. The feature is still unimplemented: craft-parts' SnapPackage only parses name/channel (no revision), and rockcraft's schema documents stage-snaps as plain channel strings. Recent activity (last comment 381 days ago) shows it's not stale, but it needs maintainer assessment.

Impact: 50 Quick Win: 22.5 Staleness: 45 Complexity: 55 Confidence: 75 Support Request: 10

Issue body

### What needs to get done We are currently able to specify a channel for `build-snaps` or `stage-snaps` as follows: ``` parts: charmed-mysql: stage-snaps: - 8.0/edge ``` However, we are unable to specify a specific revision of a snap with the above syntax ### Why it needs to get done We have snaps in the Data Platform team that track a major version of a database (e.g. `charmed-mysql/8.0`). However, the `edge` risk of the channel can be either `8.0.33` or `8.0.34` based on the snap build date Since we are using `stage-snaps` to install the binaries of the snap into our ROCK, we need a way to specify a particular revision of the snap to install from in our rockcraft.yaml file.
